The present invention relates to a method of marking shoe parts at the same time, or as part of the cycle of operations, during which, the shoe part in ornamented by perforating, cutting out, or the like.

Shoes designed particularly for women's wear are usually ornamented by the cutting out of open work patterns in the upper thereof, or by perforating designs therein. This ornamentation is effected either on a flat blank or on the upper, after it has been closed, but prior to the complete assembly of all parts of the shoe. When the ornamentation is accomplished in the blank it is generally done on a machine of the flat bed type on which the work is laid on a flat support, and when the upper is closed prior to the ornamentation, it iscutout generally on a universal type of cutout machine, which type may, however, operate on flat work as well as on closed uppers.

For various reasons, such as facilitate subsequent operations and assembly of the ornamented blank or upper, it is necessary to place marks on the blank, such marks taking the form of guide lines for stitching or as an outline upon one blank to indicate the position in which another part is to be applied, or as a guide line for subsequent perforations. It may be found desirable to place further ornamentation such as a stamped design on the shoe part. As a matter of fact such stamped design may not only be an ink mark, but

' could be formed by the use of impression papers of various kinds, such as gold leaf, silver leaf, colored leaves, etc. The ink marking might be left on in some cases to imitate a stitch as distinguished from a guide line for subsequent stitching.

Where heretofore the application of this additional markinghas required a separate handling of the work from the handling necessary to accomplish the perforating thereof, it is an object of the present invention to devise a method wherein the extra handling of the work is eliminated and additional time saved by performing the operation of marking simultaneously with the perforation of the work, or as a part of the cycle of operations necessary to perforate the shoe part. In marking work heretofore two general methods have been brought into play, first, an independent marking of the work with ink, and second, a marking by means of an impression, or partial cutting into the leather. This latter form of marking has been effected either separately from the main ornamentation of the shoe part, or as a part of the cycle of operation but has been found to be unsatisfactory except when a flat bed type of machine is used. Even in a machine of this type, the results obtained are more or less unsatisfactory, for such a method of marking is limited to flat bed dies and cannot satisfactorily be accomplished with a universal machine, and furthermore, marking by indentation or partial cutting out is objectionable, for the reason that there are a great many different kinds of leather which cannot be marked satisfactorily by mere impression.

The combination cutout and marking dies having impression markers as used under present practice are limited to certain kinds of material. Thin hard surface leathers, such as kid as used in the manufacture of women's shoes, do not take an impression very readily, whereas comparatively heavy leathers, such as calf skin, which are used in the manufacture of mens shoes can be marked in this manner. As a consequence the use of combination cutout, perforating, marking and impression dies is limited to factories manufacturing, for the most part, mens and boys medium and cheap shoes, where rather heavy calf skin is used. Patent leather also takes a rather good impression, but kid skins cannot be successfully marked, nor can any of the fancy embossed leathers, or such leathers as snake, alligator, etc., where the finish of the leather does not allow for an ordinary indented mark to be readily seen by the operator, particularly when the marked leather is in position to be stitched, or for an applique or other part to be aligned thereon, etc., and in such a position that unless the mark or indentation is of sufficient depth in the material as to make it readily recognizable.

Another objection to methods using impression marking, arises when varying thicknesses of leather are used. It is impractical to mark and with the resilient means is adjusted to mark and cutout properly on a light piece of calf skin, it

would probably cutout a heavy piece also but the indented mark would be so deep as to mar or cut the material and ,vice versa. This is due to the fact that when working on thin leathers, when the cutting operation has been completedand the die has been forced through the material, the

marking element must be exerted against the surface of the leather, with the proper amount leather, then with the same setting, a thick piece of leather will create too much pressure causing the leather to be cut, assuming that thethin and thick pieces of leather are of the same character. When different characters of leather are marked, even though they may be of the same thickness, it may be necessary to exert more pressure on one piece of material than on another piece.

Under such conditions, the relative position of the marking edges of the impression marker and the cutting edges of the die will be relatively the same on these two pieces, but the pressure exerted will be different if these two pieces of the same thickness require different amounts of pressure to produce the desired impression.

As a consequence of these requirements, it follows that the marking die must be either automatically adaptable to such varying conditions, or it must be changed to meet such conditions. It is impractical to use a die that requires changes under these varying conditions, and heretofore no one has produced a cutout and impression marker die that will meet these conditions.

It is for these reasons that recourse has been had to ink marking of leather, but as stated above, while ink marking methods and machines are well known per se, it has heretofore been found impractical to combine an ink marker with either the flat bed machine or the universal type of machine, thus necessitating an additional handling of the work for the marking step.

By the method of this invention all of the objection and disadvantages of previous methods are eliminated, and it is possible to mark and perforate or cutout any kind of material regardless of its finish or thickness, and regardless of whether or not it is flat or fitted work. The use of ink permits a very legible marking which .is readily followed by an operator and at the same time does not prevent a good clean perforation, and requires no pressure for indenting the work, thus avoiding the objections to impression markers.

For purposes of illustration of one form of machine which lends itself readily to this method, reference may be made to the patent to Freeman No. 1,681,033, dated August 14th,- 1928, in which a universal type of cutout machine is described. Such a machine is illustrated in the accompanying drawings, of which:-

Fig. 1 represents a front elevation; and

Fig. 2 represents a side elevation.

It will be observed that in this machine as modified to carry out the present method, there is provided a frame 10 having a work support 12. This support will be preferably in the form of a horn or anvil so that either flat or fitted work may be placed thereon. The top surface of the support may be faced with a soft material such as brass, which will not be injurious to the cutting edges of the perforating die in case there is con tact between the two. Across this surface a paper strip may be fed to function as backing material for the cutting edges of the die, thereby insuring a good clean cut, the paper being automatically fed after each cutting operation by a suitable mechanism indicated generally at 14.

In order to properly gauge and position the work for cutting out operations, a mask 16 may be utilized, this mask having a gauging edge adapted to coincide with some portion of the work and thus indicate to the operator when the work is properly positioned. As described in the Freeman patent above noted, this mask may be solid and have its outer edge adapted to function as a gauging edge or it may be cutout to permit passage of a die therethrough and an internal edge might be utilized as a gauge. In some forms of work, both the internal and outer edges may be used if found desirable.

This mask may also function as a clamp or hold down for the work during actual cutting operations thereon.

Mounted to reciprocate relative to the support 12 is a plunger having a die indicated generally at 18 and including a die holder 20. The die will include cutting edges 21 attached to a supporting plate 23. The plunger will be reciprocated periodically from a driving pulley 22 controlled by a single revolution clutch 24, which may be of the type disclosed in Patent No. 1,681,033 above mentioned, and which is operated by a clutch lever 26. This lever 26 is actuatedby a mechanism hereinafter described and causes the clutch to connect the driving pulley to the actuating mechanism whereby the pulley will actuate the plunger for a single revolution and cause the die to move down and back during this revolution. In order to impress and mark with ink on the work, a marking element 30 is provided on the die 18 for movement up and down with the die. This element preferably is in the form of a plate having a protruding abutment 31 and may be mounted on the unit 18 by means of studs 33 having spring 35 tend to normally maintain the plate 30 in advance of the cutting edges 21. A roll 32 for inking this marker is mounted on a carriage 34 and the carriage is geared to move beneath the marker 30 when the latter is raised and for movement to inoperative position when the marker descends. It will be observed that the marking device preferably is extended ahead of the cutting edges of the die, so that the cutting edges of the die are not inked, although the cutting die could be set so that it would be inked, if thought desirable. An advantage of the location of the marking device in advance of the cutting edges of the die resides in the-fact that the marking die or plate will act as a stripper for the cutting or perforating die: This function is possible, because of the fact that the location of the marking plate in advance of the cutting edges perforce places the plate between the work and the cutting edges. To operate the inking device,'there is provided a pulley 36 controlled by another single revolution clutch 38, like that at 24 and this pulley when connected to the actuating mechanism of the inker is effective to reciprocate the carriage under the marking element and back during a single revolution.

It is obvious that the roll arrangement described above, while forming a preferred em- The general sequence of operations consists in placing the work on the support 12, accurately 'such element has been inked, rather than before.

The mask 16 is mounted for movement relative to the die unit 18 by studs 37 which extend through sleeves 39 forming part of the die unit 18, the studs 37 being headed at their upper ends to limit movement of the mask in one direction and being provided with collars 41 for engagement with a lever 48 hereinafter described.

In order that work may be inserted and removed without damage to the operator a lever 48 is provided to raise and lower the mask for the insertion of and subsequent clamping of a shoepart. This lever is pivoted about a shaft 50 and forms one end of a bell crank having a 'second arm 52, which arm engages a clutch looking bar 54. This bar in turn engages a clutch wedge 40 and thereby prevents actuation by the driving pulley 36 at such time as the mask is raised.

To actuate the levers 48 and 52 a treadle 56 is utilized, same being connected to the shaft 50. Upon actuation of the treadle 56 the mask will be lowered and the clutch locking mechanism unlocked.

An additional treadle 58 controlling operation of the machine is connected to actuate the clutch wedge 40, thereby to connect the driving pulley 36 by means of an eccentric strap 42 to a gear segment 44 for engaging a rack 46, which is formed as a part of the carriage 34. The shaft on which this gear segment 44 is mounted also supports an arm carrying a roll 28 which is adapted to engage a lever 26 above described, which lever controls the clutch 24. A spring actuated clutch wedge 25 is controlled by the clutch lever 26 and upon actuation of the lever by the roll 28, the wedge is released and the clutch 24 brought into operation to connect the driving pulley 22, for a single revolution to the plunger actuating mechanism. It will thus be seen that a chain of automatically acting connections is provided from the treadle 58 to the plunger actuating mechanism and including the inker mechanism, and that an additional mechanism is provided for controlling movements of the mask which act to lock said chain of connections against operation until the work is properly positioned.

The work support 12 is provided with an adjustable mechanism such as a micrometer adjusting gauge 60 whereby it may be raised and lowered to meet variable conditions, difierent thicknesses of leather, etc. This support will preferably be interchangeablewith other supports of varying heights to take different sizes or style of work. Insofaras the features of the cutout machine are concerned, reference may be made to my aforesaid Patent No. 1,681,033.

It will be observed that the head of the machine is adapted to contain the mechanism for moving the die holder up and down, and that the dies in the illustrated embodiment aremounted on the underside of the holder which is attached to the plunger. It may be desirable under certain conditions to mount the dies in various other arrangements, for example, on the work support or to separate the marking elements from the cutting dies. It has been found feasible-to place the marking elements on the mask itself and it'is to be understood that any suitable arrangement of machinery which will satisfactorily carry out the method may be utilized.

In the form of machine described herein the dies are removably mounted on the plunger so that different dies can be replaced or removed. Automatic mechanism may be provided for locating the die in proper position and holding it against the plunger. Owing to the weight of the die this is important as the die should not be loosely held in place in such a position. Preferably the holding mechanism will be of a nature to grip the die and hold same tightly in position. It may be further observed that the mechanism for actuating the plunger has a toggle motion, and as stated above that the clutch controlling this toggle mechanism is locked against operation, except when the gauging means on the die are in such position as to be ready for the cutting out or marking operation. The gauge or mask will usually be attached in such a manner as to form a part of the die, and will be provided with openings the edges of which will act as a gauge, or with abutments or solid gauges against which the work rests when properly positioned.

Usually the gauging means will function in advance of both the marking die and cutting die and with sufiicient space between the work and the die as to permit the operator a full view of the work.

From the foregoing the operation of the machine will be clear; with the plunger and the gauging mask in raised position the operator will position the work on the support. The mask or gauge will then be lowered to a position sufficiently close to the work to insure accurate gauging therewith. Y I

When the mask or gauge has been lowered to a position where it will clamp the Work, the clutch 38 will be unlocked and ready for actuation through the medium of the treadle 58. Upon actuation of such treadle the clutch 38 will provide for actuation of the inking mechanism, and the roll 32 will be projected under the marking element. Should the operator still have her fingers under the die this mechanism will act to clear the space under the die just previous to the time the die descends, and would sweep away the fingers, or any other obstacle that should happen to be there. Therefore, it not only acts as an inkingv device,.but also acts as a safety device. It will function in this manner even though the machine is being used only for perforating and no ink is applied to the roll. In fact the roll may be shaped or the roll carriage may mount a device particularly shaped to perform this function of sweeping away the-fingers or any other obstruction from the path of the cutter. While this action is taking place the connections from the clutch 38 to the clutch 24 are being actuated, and as the roll 32 reaches its inoperative position the mechanism connected to the plunger ,will come into play and the die willdescend, operate on the work and return.

It will be obvious that the machine will operate to out without inking, or to mark without outting, or to both out and mark the work, and that the cutting and marking may be accomplished simultaneously or successively in any desired order, and automatically. It may be found desirable to accomplish the cutting and marking successively by operating the machine so that the work could either first be cut out and the die moved out of operating. position, and then the marking operation be effected, with the idea in mind thatthe marking and cutting elements be so operated as not to interfere with each other. The Work may be held or placed in one position during these successive operations, and it would make no difference whether the work was marked or cut first. This mode of operation is desirable with certain types of dies where the markis so close to the cutout or perforation that it is impossible to mount the marking plate on the die as indicated and hence a plurality of successive operations will be found more practical. This will be more apparent when it is considered that the shanks of the die are bevelled as the cutting die approaches the cutting edge and during the cutting out operation with a combined marking and cutting die, this portion of the die must pass through the marking element. The marking element has to have a certain amount of support and between these two features it means that marks can only be placed so close to the design.

In cutting out a piece of work, the work has to be gauged or aligned with reference to the die and when marking the work it again has to be gauged, for the cutting and marking operations are separate and distinct from one another. In practice it is very diflicult, no matter how accurately thegaugegis made to position the work, which is usually of light material, in such a manner that the cutting and marking are exactly aligned and thiscauses a lot of work to be spoiled. An essential advantage of the present machine resides in the fact that regardless of whether the marking and cutting out are performed simultaneously or as a continuous operation, it is possible to avoid the separate gauging for marking and cutting, thereby insuring always perfect alignment as'the work is only positioned once with respect to the gauge.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent of the United States, is:
